Abstract (en)
This disclosure provides an ultrasound detection device (1) for detecting a target object by using a plurality of echo signals acquired by a plurality of ultrasound signals at different frequencies. The device includes a reflection intensity difference calculation module (41) for calculating difference values of the echo signals at different frequencies, a histogram calculation module (42) for calculating a histogram of the difference values, and a similarity calculation module (43) for calculating a similarity of a characteristic between the histogram of the difference values and a reference histogram that is set for every classification of the target object. A display module (50) displays data from which a classification of the target object can be determined.
